摘要：
A thorough design methodology of one and two degrees of freedom Helmholtz resonators leading to optimised transmission loss is described and validated in this paper. Numerical simulations of acoustic wave propagation in pipelines fitted with designed resonators have shown great agreement with analytical modelling and experimental tests. The Helmholtz resonator concept has been analysed in various configurations to evaluate the effect of the size and arrays on the overall noise attenuation performance. Using this method to directly dimension geometry aspects of the resonators followed by numerical computation of the sound pressure levels has shown that considerable sound attenuation could be achieved.
